We report the serendipitous discovery of two objects close in projection wi
th fairly strong emission lines at long wavelength (lambda similar to 9190
Angstrom). One (A) seems not to be hosted by any galaxy brighter than V-555
= 27.5, Or I-814 = 26.7 (Vega-based 3 sigma limits in 1." 0 diameter apert
ures), while the other line is associated with a faint (I-814 similar or eq
ual to 24.4) red galaxy (B) offset by 2." 7 and 7 Angstrom spectrally. Both
lines are broad (FWHM approximate to 700 km s(-1)), are extended spatially
, and have high equivalent widths [W-lambda(obs)(A) > 1225 Angstrom, 95% co
nfidence limit; W-lambda(obs)(B) approximate to 150 Angstrom] No secondary
spectral features are detected for galaxy A. Blue continuum and the margina
l detection of a second weak line in the spectrum of galaxy B is consistent
with [O II] (the strong line) and Mg II (the weak line) at z = 1.466. By a
ssociation, galaxy A is likely at z = 1.464, implying a rest-frame equivale
nt width of the [O II] emission line in excess of 600 Angstrom and a projec
ted separation of 30 h(50)(-1) kpc for the galaxy pair. Conventional wisdom
states that isolated emission lines with rest-frame equivalent widths larg
er than similar to 200 Angstrom are almost exclusively Ly alpha. This moder
ate-redshift discovery therefore compromises recent claims of high-redshift
Ly alpha emitters for which other criteria (i.e., line profile, associated
continuum decrements) are not reported. We discuss observational tests to
distinguish Ly alpha emitters at high redshift from foreground systems.
